Answer:
a=3/4
Explanation:
1. Get 2/3a by itself.
 •Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.
 •Because you only add and subtract like denominators
 
 This will make it look like:
2/3a - 1/6 = 2/6
Then, add 1/6 to both sides to get 2/3a by itself.
 It'll look like this:
2/3a = 3/6
2. Get a by itself.
 •Multiply the reciprocal (opposite) of 2/3 to get a alone. 
This will look like:
 (3/2) • 2/3a = (3/2) • 3/6
 a = 18/24
3. Simplify. 
 Find the largest number that can simplify the equation.
 For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.
 But the largest number you can divide both sides by is 6. 
 18 ÷ 6 = 3 and 24 ÷ 6 = 4.
 3/4.
